04 / Acceptance and handover
Prove the result under a representative production condition
Measure side-stream flow and composition through boundary additions, trend load and temperature, and verify stable return, rapid bulk dilution, no deposits and repeatable final properties. Sample spatially and by time to verify lump removal, hydration, viscosity, particle distribution, temperature, air pickup, cycle time, heel and repeatability. Put the sample or test material, method, instrument, production state, duration, limit, witnesses, retained record and deviation authority in the protocol before testing begins. Requalify when a product, package, site, speed or connected system invalidates the accepted basis.
